FIELD

Various embodiments of the disclosure relate generally to transaction processing systems. More specifically, various embodiments of the disclosure relate to a method and a system for conducting transactions using an electronic chip.

BACKGROUND

Emergence of transaction cards has revolutionized the way transactions are performed at terminal devices, such as automatic teller machines (ATMs), point-of-sale (POS) devices, or the like. A transaction conducted using a transaction card involves authentication of a user conducting the transaction and authorization of the transaction. Typically, an issuer of the transaction card is responsible for authenticating the user and authorizing the transaction. For authentication, the user provides an authentication parameter associated with the transaction card at the terminal device. The authentication parameter may be a one-time password (OTP), a personal identification number (PIN), or a biometric feature such as, a fingerprint, a faceprint, a voiceprint, a retina scan, or the like. The terminal device communicates the authentication parameter to the issuer. The issuer then authenticates the user based on the authentication parameter and communicates an authentication response, indicating a result of authentication, to the terminal device. Such to-and-fro communication between the issuer and the terminal device increases the processing time for the transaction and may cause inconvenience to the user, especially in times of an emergency. Moreover, when there is limited network connectivity between the terminal device and the issuer, the authentication process may fail and the transaction may be declined.

Offline authentication by using contactless transaction cards at the terminal device is a known solution to overcome the abovementioned problem. A contactless transaction card is usually embedded with an electronic chip that locally stores an authentication parameter associated with the contactless transaction card and details of the contactless transaction card. The electronic chip is a near field communication (NFC) enabled chip that communicates with the terminal device for facilitating offline authentication when a transaction is conducted. However, such contactless transaction cards are susceptible to skimming frauds, where fraudsters copy the details stored in the contactless transaction cards using portable NFC readers without the knowledge of the users and duplicate the cards for performing fraudulent transactions.

In light of the foregoing, there exists a need for a solution that solves the abovementioned problems and provides a mechanism to conduct secure and hassle-free transactions.

Overview

In current transaction systems, when a user initiates a transaction at a terminal device, the user provides an authentication parameter to the terminal device for authentication. The terminal device communicates the authentication parameter to an issuer associated with the transaction for authenticating the user. The involvement of the issuer in carrying out the authentication process for various transactions not only increases a processing overhead of the issuer but also increases the processing time for the transactions. Although contactless transaction cards have the provision of offline authentication that reduces the processing overhead of the issuer and the processing time for the transactions, the contactless transaction cards are susceptible to skimming frauds.

Various embodiments of the disclosure provide a method and a system to solve the abovementioned problems by allowing transactions to be conducted using an electronic chip. An electronic chip issuer (for example an issuer server or a third-party server) issues the electronic chip to a user for enabling the user to conduct transactions at a terminal device. Examples of the terminal device may include an automatic teller machine (ATM), a bunch note acceptor (BNA), a currency recycler, a point-of-purchase (POP) device, a point-of-interaction (POI) device, a point-of-sale (POS) device, or the like. In one example, the electronic chip is placed on or attached to a wearable device of the user. In another example, the electronic chip is placed under or attached to an epidermis layer of skin of the user. The user adds payment modes to the electronic chip by electronically storing the details of the payment modes in the electronic chip. Examples of the payment modes may include transaction cards and/or digital wallets. The user further stores one or more sample authentication parameters (e.g., a fingerprint, a retina scan, a faceprint, a voiceprint, or the like) of the user in the electronic chip. When the user wants to conduct a transaction at the terminal device using the electronic chip, the user selects a chip-based transaction option displayed on a graphical interface of the terminal device. The user provides a first authentication parameter to the terminal device. Examples of the first authentication parameters include, a fingerprint, a retina scan, a faceprint, a voiceprint, or the like. The terminal device communicates an authentication request including the first authentication parameter to the electronic chip. The electronic chip authenticates the user by comparing the first authentication parameter with the sample authentication parameters stored in the electronic chip. Based on a match between the first authentication parameter and one of the sample authentication parameters, the electronic chip generates an authentication response. The authentication response indicates whether the authentication of the user was successful. When the authentication is successful, the authentication response includes details of one or more payment modes of the plurality of payment modes that are added to the electronic chip. The terminal device further displays the one or more payment modes on the graphical interface to the user for selection. Based on a selection of a payment mode by the user, the terminal device generates an authorization request for authorization of the transaction and communicates the authorization request to an issuer of the selected payment mode. The authorization request includes details of the selected payment mode and transaction details of the transaction. The user may be allowed to select more than one payment modes from the displayed payment modes for conducting a split transaction (i.e., splitting a transaction amount of the transaction across multiple payment modes). The issuer authorizes the transaction based on the authorization request.

Thus, the user is authenticated offline without the involvement of the issuer, which reduces the processing overhead of the issuer and the processing time of the transaction. Since the electronic chip is either placed on the user's wearable device or placed under the user's skin, likelihood of skimming fraud is reduced. In addition, details stored in the electronic chip may only be retrieved by way of an authentication parameter of the user that matches one of the sample authentication parameters stored in the electronic chip, thus making the electronic chip immune to skimming fraud.

Terms Description (in Addition to Plain and Dictionary Meaning)

Transaction is an exchange of funds between two or more parties. For example, the transaction may include transferring a transaction amount from a user to a merchant, when the user makes a purchase from the merchant. In another example, the transaction may include dispensing cash, at an ATM, equivalent to a transaction amount debited from an account of the user based on a request from the user.

Payment mode is means of payment, such as a debit card, a credit card, a prepaid card, a gift card, a promotional card, a contactless card, a digital wallet, and/or like, that is linked to an account and holds identification information of the account. The payment mode may be used to perform transactions, such as deposits and cash-withdrawals, credit transfers, purchase payments, or the like, from the account to which it is linked. The payment mode may be a physical payment mode or a virtual payment mode that is electronically stored in a user device.

Terminal device is a computing device affiliated with a financial institution, (hereinafter “acquirer”). The terminal device enables users to perform various electronic transactions, such as cash withdrawals, cash deposits, purchase payments, funds transfer, or the like. Examples of the terminal device include, but are not limited to, a POS device, a POP device, a POI device, an ATM, a BNA, a currency recycler, or the like.

Acquirer is a financial institution where accounts of several merchants are established and maintained. The acquirer is further associated with a terminal device. The acquirer communicates an authorization request for a transaction initiated at the terminal device to a payment network.

Authorization request for a transaction refers to a request by which an acquirer ensures that the transaction is valid and authorized by a corresponding issuer. The acquirer communicates the authorization request to the issuer for authorization. The authorization request is pursuant to one or more standards for the interchange of transaction messages, such as the ISO8583 standard, and includes various fields, such as data elements (DEs), for storing transaction details of the transaction.

An electronic chip is a near field communication (NFC) enabled microchip that allows a user to conduct transactions at terminal devices. The electronic chip may be a microchip (for example, radio frequency identification tag, RFID tag) embedded in a wearable device of the user or may be a microchip implant that is placed under or attached to an epidermis layer of the skin of the user. The electronic chip may include a memory element for storing information such as details of various payment modes (e.g., details of a transaction card or a digital wallet) of a user and various authentication parameters (e.g., a fingerprint, a faceprint, a voiceprint, or a retina scan) of the user. The electronic chip is capable of communicating with other NFC enabled devices to transmit or receive information. For example, the electronic chip communicates with an NFC enabled terminal device for authenticating the user who has initiated a transaction.

A bi-directional communication link is a short-range wireless link established between two NFC enabled devices. For example, an electronic chip and a terminal device may communicate with each other by way of a bi-directional communication link established therebetween.

Authentication parameter refers to means of authenticating a user for a transaction. Examples of the authentication parameter may include a fingerprint, a faceprint, a voiceprint, a retina scan, a specific gesture, or the like. A first authentication parameter provided by the user is compared with a second authentication parameter stored in an electronic chip. When the first and second authentication parameter match, authentication is determined to be successful.

FIG. 1 is a block diagram that illustrates an exemplary environment 100 for conducting transactions using an electronic chip 102, in accordance with an exemplary embodiment of the disclosure. The environment 100 includes a user 104 associated with the electronic chip 102, a user device 106 of the user 104, a terminal device 108, an acquirer server 110, a payment network server 112, and an issuer server 114. The user device 106, the terminal device 108, the acquirer server 110, the payment network server 112, and the issuer server 114 communicate with each other by way of a communication network 116 or through separate communication networks established therebetween. The electronic chip 102 and the terminal device 108 communicate with each other by way of a bi-directional communication link 118 established therebetween.

The electronic chip 102 is issued to the user 104 by an electronic chip issuer. In one example, the electronic chip issuer may be a financial institution where a user account of the user 104 is maintained. In another example, the electronic chip issuer may be a third-party service provider who is in partnership with various financial institutions. The electronic chip 102 includes suitable logic, circuitry, interfaces, and/or code, executed by the circuitry, for enabling the user 104 to conduct transactions. The electronic chip 102 is a near field communication (NFC) enabled microchip. NFC is a short-range wireless communication standard which enables communication between various devices (e.g., the electronic chip 102 and the terminal device 108 or the electronic chip 102 and the user device 106) when the devices are within a first distance (i.e., a pre-determined distance) from each other. The first distance refers to a communication range for an NFC enabled device (e.g., the electronic chip 102) to communicate with other NFC enabled devices (e.g., the user device 106 and the terminal device 108). For example, if the first distance is 10 centimetres (cms), the electronic chip 102 and the terminal device 108 should be within a range of 10 cms from each other for communication. In one embodiment, the electronic chip 102 may be a microchip (for example, an RFID tag, or the like) embedded in a wearable device of the user 104 (as shown in FIG. 2A). In another embodiment, the electronic chip 102 may be a microchip implant (for example, an RFID tag, or the like) that is placed under or attached to an epidermis layer of the skin of the user 104 (as shown in FIG. 2B).

In one embodiment, the electronic chip 102 may be initially inactive when issued to the user 104, and the electronic chip issuer may provide an activation key to the user 104 for activating the electronic chip 102. The electronic chip 102 is activated by the user 104 using a service application running on the user device 106. The service application may serve as an interface for the user 104 to communicate with the electronic chip 102. In one example, the user 104 uses the service application running on the user device 106 as an entry point to provide the activation key to the electronic chip 102. On receiving the activation key, the electronic chip 102 is activated for use.

After the electronic chip 102 is activated, the electronic chip 102 receives one or more sample authentication parameters of the user 104 from the user device 106. The user 104 may provide the sample authentication parameters to the electronic chip 102 by way of the service application running on the user device 106. The sample authentication parameters may include one or more fingerprints of the user 104, a faceprint of the user 104, a voiceprint of the user 104, a retina scan of the user 104, a specific gesture, or the like. The electronic chip 102 further receives details of various payment modes of the user 104 from the user device 106 by way of the service application. Examples of the payment modes may include transaction cards or digital wallets. For example, details of a transaction card may include a unique card number, an expiry date, a card security code, and a card type of the transaction card. Details of a digital wallet may include a wallet ID, a wallet number, or the like, of the digital wallet. The electronic chip 102 stores the sample authentication parameters and the details of the payment modes therein in an encrypted format. After the electronic chip 102 is activated, and the sample authentication parameters and the details of the payment modes are stored in the electronic chip 102, the electronic chip 102 may be utilized by the user 104 for conducting transactions at the terminal device 108. It will be apparent to a person of ordinary skill in the art that a plurality of electronic chips similar to the electronic chip 102 may be issued to a plurality of other users for conducting transactions at the terminal device 108 or any other terminal device.

The user device 106 is a communication device of the user 104. The user device 106 may serve as an interface for the user 104 to store information (e.g., the sample authentication parameters and the details of the payment modes) in the electronic chip 102 and update the stored information. The user device 106 may have the service application running thereon that allows the user 104 to store the information in the electronic chip 102 and update the stored information. The user device 106 may be utilized by the user 104 to communicate the activation key to the electronic chip 102 for activating the electronic chip 102. Examples of the user device 106 may include a smartphone, a personal computer, a tablet, a phablet, or the like.

The terminal device 108 includes suitable logic, circuitry, interfaces, and/or code, executed by the circuitry, to allow users (such as the user 104) to perform transactions from corresponding user accounts. The terminal device 108 may be associated with a financial institution, such as an acquirer. Examples of the terminal device 108 may include an ATM, a BNA, a currency recycler, a POP device, a POI device, a POS device, or the like. The terminal device 108 presents a chip-based transaction option for enabling the user 104 to conduct transactions using the electronic chip 102. The terminal device 108 is an NFC enabled device that is configured to detect the presence of the electronic chip 102 when the electronic chip 102 is within a communication range (for example, the first distance) of the terminal device 108. The terminal device 108 is further configured to establish the bi-directional communication link 118 between the terminal device 108 and the electronic chip 102 when the electronic chip 102 is detected within the communication range of the terminal device 108. The terminal device 108 communicates with the electronic chip 102 by way of the bi-directional communication link 118 and enables the user 104 to conduct transactions using the electronic chip 102. The terminal device 108 communicates with the electronic chip 102 for authenticating the user 104 for a transaction and receiving the details of the payment modes stored in the electronic chip 102 for processing the transaction.

The acquirer server 110 is a computing server that is operated by the acquirer and includes suitable logic, circuitry, interfaces, and/or code, executed by the circuitry, for processing the transactions. The acquirer server 110 may receive various authorization requests for transactions from the terminal device 108 and communicate the authorization requests to the payment network server 112 for further processing of the transactions.

The payment network server 112 is a computing server that is operated by a payment network and includes suitable logic, circuitry, interfaces, and/or code, executed by the circuitry, for processing the transactions. The payment network server 112 represents an intermediate entity between the acquirer server 110 and the issuer server 114 for authorizing and funding the transactions. The payment network server 112 may receive the authorization requests from the acquirer server 110 and communicate the authorization requests to the issuer server 114.

The issuer server 114 is a computing server that is operated by the issuer and includes suitable logic, circuitry, interfaces, and/or code, executed by the circuitry, for processing transactions. The issuer is a financial institution that manages accounts of multiple users, such as the user 104. Account details of the user accounts established with the issuer are stored as account profiles in a memory (not shown) of the issuer server 114 or on a cloud server associated with the issuer server 114. The account details may include an account balance, an available credit line, details of an account holder, transaction history of the account holder, account information, or the like. The details of the account holder may include name, age, gender, physical attributes, registered contact number, alternate contact number, registered e-mail ID, or the like of the account holder.

In one embodiment, when the issuer associated with the issuer server 114 is the electronic chip issuer, the issuer server 114 may store an electronic chip identifier (ID) of the electronic chip 102 in a database. The issuer server 114 may further host the service application that is executable on the user device 106 and communicate the activation key to the user device 106 by way of the service application. The issuer server 114 may further store, in the database, an activation status of the electronic chip 102 indicating whether the electronic chip 102 has been activated using the activation key.

The issuer server 114 receives the authorization requests for the transactions from the payment network server 112. The issuer server 114 authorizes the transactions based on the authorization requests and generates authorization responses indicating whether the transactions are approved or declined. Methods for processing transactions via the issuer server 114 will be apparent to a person of ordinary skill in the art and may include processing the transaction via the traditional four-party system or the traditional three-party system. Though the issuer server 114 and the acquirer server 110 are shown as separate entities in FIG. 1, in other embodiments, where the issuer and acquirer are same, the operations performed by the issuer server 114 and the acquirer server 110 may be performed by a single entity without deviating from the scope of the disclosure. In such a scenario, the electronic chip 102 and the terminal device 108 may be associated with the same entity.

The communication network 116 is a medium through which content and messages are transmitted between the terminal device 108, the acquirer server 110, the payment network server 112, the issuer server 114, or other entities that are pursuant to one or more standards for the interchange of transaction messages, such as the ISO8583 standard. Examples of the communication network 116 include, but are not limited to, a Wi-Fi network, a light fidelity (Li-Fi) network, a local area network (LAN), a wide area network (WAN), a metropolitan area network (MAN), a satellite network, the Internet, a fiber optic network, a coaxial cable network, an infrared (IR) network, a radio frequency (RF) network, and combinations thereof. Various entities in the environment 100 may connect to the communication network 116 in accordance with various wired and wireless communication protocols, such as Transmission Control Protocol and Internet Protocol (TCP/IP), User Datagram Protocol (UDP), Long Term Evolution (LTE) communication protocols, or any combination thereof.

In operation, the electronic chip 102 is issued to the user 104 by the electronic chip issuer (for example, the issuer server 114). The electronic chip 102 may either be embedded in the wearable device of the user 104 or placed under (or attached on) the skin of the user 104. The user device 106 is utilized by the user 104 for activating the electronic chip 102, and storing the sample authentication parameters and the details of the payment modes in the electronic chip 102. After the sample authentication parameters and the details of the payment modes are stored, the electronic chip 102 is utilized by the user 104 for conducting a transaction at the terminal device 108. The user 104 selects the chip-based transaction option presented at the terminal device 108 for conducting the transaction using the electronic chip 102.

Based on the selection of the chip-based transaction option, the terminal device 108 detects the presence of any electronic chip within the first distance. When the electronic chip 102 is determined to be present within the first distance from the terminal device 108, the terminal device 108 establishes the bi-directional communication link 118 with the electronic chip 102. The terminal device 108 further prompts the user 104 to provide a first authentication parameter (e.g., a fingerprint, a faceprint, a voiceprint, or a retina scan of the user 104 and/or a specific gesture). Based on the first authentication parameter of the user 104, the terminal device 108 generates an authentication request including the first authentication parameter, and communicates the authentication request to the electronic chip 102 by way of the bi-directional communication link 118.

The electronic chip 102 receives the authentication request and compares the first authentication parameter with the sample authentication parameters stored in the electronic chip 102. Based on the comparison between the first authentication parameter and the sample authentication parameters, the electronic chip 102 generates an authentication response. When the first authentication parameter matches any of the sample authentication parameters, the authentication is successful and the authentication response includes the details of the payment mode/s that are stored in the electronic chip 102. The electronic chip 102 communicates the authentication response to the terminal device 108 by way of the bi-directional communication link 118. Based on the received authentication response, the terminal device 108 renders a graphical interface to display the payment mode/s to the user 104. One or more of the displayed payment modes are selected by the user 104 for carrying out the transaction. Based on the selection of the payment mode/s, the terminal device 108 generates an authorization request for authorizing the transaction. The terminal device 108 communicates the authorization request to the acquirer server 110. The method for authorizing and processing the transaction will be apparent to a person of ordinary skill in the art and may include processing the transaction via the traditional four-party system or the traditional three-party system.

FIG. 2A represents a first exemplary scenario 200A for placement of the electronic chip 102, in accordance with an exemplary embodiment of the disclosure. As shown in FIG. 2A, the electronic chip 102 is embedded in a wearable device 202. The wearable device 202 is shown to be a wrist-band worn by the user 104. In other embodiments, the wearable device 202 may be a watch, an arm band, a pair of glasses, a ring, a cap, or any other device that is capable of being integrated with the electronic chip 102.

FIG. 2B represents a second exemplary scenario 200B for placement of the electronic chip 102, in accordance with another embodiment of the disclosure. As shown in FIG. 2B, the electronic chip 102 is placed under or attached to the skin of a thumb 204 of the user 104. For example, the electronic chip 102 may be implanted under the skin of the thumb 204. In other embodiments, the electronic chip 102 may be placed under or attached to the skin of any other body part of the user 104 based on a consent of the user 104, without deviating from the scope of the disclosure.

FIG. 3 is a process flow diagram 300 that illustrates an exemplary scenario for activating and storing details in the electronic chip 102, in accordance with an exemplary embodiment of the disclosure.

The user 104 utilizes the user device 106 to log into a service application 302 hosted by the issuer server 114. The user 104 may log into the service application 302 by providing login details, such as a username and a password, of the user 104 (as shown by arrow 304). The user 104 utilizes the service application 302 for requesting the issuer server 114 to provide an activation key for activating the electronic chip 102. The user device 106 communicates the request for the activation key to the issuer server 114 (as shown by arrow 306). The request may include the electronic chip ID of the electronic chip 102. The issuer server 114 receives the request from the user device 106 and communicates the activation key associated with the electronic chip 102 to the user device 106 (as shown by arrow 308). For example, based on the received request, the issuer server 114 dynamically generates the activation key for the electronic chip 102, and stores the activation key in the database. After storing the activation key, the issuer server 114 transmits a message, indicating the activation key, to the user device 106. The message may be in the form of an electronic mail (e-mail), a short message service (SMS), an interactive voice response (IVR) call, or the like. The user 104 further utilizes the user device 106 to establish a communication link (i.e., similar to the bi-directional communication link 118) between the electronic chip 102 and the user device 106 (as shown by arrow 310).

When the communication link between the electronic chip 102 and the user device 106 is established, the user 104 enters the activation key through the service application 302 (as shown by arrow 312). The user device 106 communicates the activation key and the electronic chip ID of the electronic chip 102 to the issuer server 114 for validation (as shown by arrow 314). The issuer server 114 then validates the activation key received from the user device 106 (as shown by arrow 316). For validating the received activation key, the issuer server 114 refers to the database including all the activation keys generated by the issuer server 114 and retrieves the activation key that corresponds to the electronic chip 102. The issuer server 114 then compares the activation key retrieved from the database and the activation key received from the user device 106. In a scenario, where both the activation keys match, the issuer server 114 determines that the activation key received from the user device 106 is valid.

The issuer server 114 communicates an activation command to the user device 106 when the activation key received from the user device 106 is determined to be valid (as shown by arrow 318). The user device 106 communicates the activation command to the electronic chip 102 for activating the electronic chip 102 (as shown by arrow 320). Based on the activation command, the electronic chip 102 is activated (as shown by arrow 322). The electronic chip 102 communicates an activation notification to the user device 106 (as shown by arrow 324). When the user device 106 receives the activation notification indicating successful activation of the electronic chip 102, the service application 302 allows the user 104 to add to the electronic chip 102, various payment modes of the user 104 or payment modes of other users from which the user 104 is authorized to perform transactions. The payment modes may correspond to transaction cards and/or digital wallets. The payment modes may be associated with different issuers and different payment networks. The user 104 is required to provide the details of the payment modes to the electronic chip 102 for adding the payment modes to the electronic chip 102. The user 104 is further required to provide one or more sample authentication parameters for each payment mode.

The user 104 may utilize the user device 106 for providing the sample authentication parameters and the details of the payment modes (as shown by arrow 326). In one embodiment, the user 104 may provide different sample authentication parameters for different payment modes. In another embodiment, the user 104 may provide one or more sample authentication parameters that are applicable for all the payment modes that the user 104 wants to add to the electronic chip 102. The sample authentication parameters may include the fingerprints, the faceprint, the voiceprint, the retina scan of the user 104 and/or a specific gesture. In one example, when one of the sample authentication parameters is a fingerprint, the user 104 may provide the fingerprint by using a fingerprint scanner on the user device 106. In another example, when one of the sample authentication parameters is a faceprint, a camera of the user device 106 may be utilized to scan the faceprint of the user 104. Likewise, the camera may be utilized to scan the retina or the specific gesture of the user 104. The user device 106 communicates the sample authentication parameters and the details of the payment modes provided by the user 104 to the electronic chip 102 (as shown by arrow 328). The electronic chip 102 then stores the sample authentication parameters and the details of the payment modes therein (as shown by arrow 330). In one embodiment, the electronic chip 102 may store the sample authentication parameters and the details of the payment modes in an encrypted format to ensure data security. Storing the details of the payment modes in the electronic chip 102 corresponds to adding the payment modes to the electronic chip 102. The electronic chip 102 further links the sample authentication parameters to the payment modes added to the electronic chip 102. In one example, a fingerprint of the user 104 is linked to a first transaction card that is added to the electronic chip 102 and the faceprint of the user 104 is linked to a first digital wallet that is added to the electronic chip 102. In another example, the fingerprint of the user 104 is linked to the first transaction card and the first digital wallet. In one embodiment, the user 104 may be allowed to designate one of the added payment modes as a default payment mode. In another embodiment, the electronic chip 102 may automatically designate one of the added payment modes as the default payment mode based on various selection parameters (as described in FIG. 4A).

In one embodiment, the activation key generated by the issuer server 114 may be associated with an expiry time. For example, the expiry time of the activation key may be 1 hour (i.e., the activation key, if not used, will expire after 1 hour). In such a scenario, if the user 104 uses an expired activation key for activating the electronic chip 102, the activation fails. After the lapse of the expiry time, the user 104 has to request the issuer server 114 for a new activation key.

In another embodiment, the activation key may be static and may be stored in the electronic chip 102 by the issuer server 114. In such a scenario, when the user device 106 receives the activation key from the issuer server 114 based on the request of the user 104, the user device 106 directly communicates the activation key to the electronic chip 102 for validation. The electronic chip 102 may compare the received activation key with the stored activation key. If the received activation key matches the stored activation key, the electronic chip 102 is activated. The electronic chip 102 may further communicate the activation notification to the user device 106. In one embodiment, the electronic chip 102 may be secured by way of a password. Thus, if the user 104 wants to update the information (e.g., the details of the payment modes and the sample authentication parameters) stored in the electronic chip 102, the user 104 is required to provide the password to the electronic chip 102 by accessing the service application 302 on the user device 106. When the password provided by the user 104 is correct, the user 104 is allowed to update the information stored in the electronic chip 102.

In one embodiment, the user 104 may be allowed to set various selection parameters (such as spending limits, allowed merchant categories, and/or the like) for the payment modes added to the electronic chip 102. In one example, the user 104 may set a spending limit for the first transaction card added to the electronic chip 102. In such a scenario, the user 104 may be restricted from spending more than the set (or assign) spending limit by using the first transaction card. In another example, the user 104 may set a merchant category, for example grocery stores, for the first transaction card. In such a scenario, the user 104 may be restricted from using the first transaction card at any other merchant except grocery stores.

In another embodiment, the details of the payment modes of the user 104 may be already stored in the electronic chip 102 by the issuer server 114 when the electronic chip 102 is issued to the user 104. In such a scenario, the user 104 only needs to activate the electronic chip 102 and store the sample authentication parameters in the electronic chip 102. Additional payment modes may be added to the electronic chip 102 by the user 104 as described in the foregoing description of FIG. 3.

FIGS. 4A-4C, collectively represent a process flow diagram 400 that illustrates an exemplary scenario for conducting transactions using the electronic chip 102, in accordance with an exemplary embodiment of the disclosure. The user 104 may have activated and stored the details of the payment modes in the electronic chip 102. The user 104 may utilize the terminal device 108 for conducting a transaction using the electronic chip 102.

The terminal device 108 renders a graphical interface for presenting the chip-based transaction option and a card-based transaction option to the user 104. The chip-based transaction option allows the user 104 to conduct the transaction using the electronic chip 102. The card-based transaction option allows the user 104 to conduct the transaction using transaction cards. The user 104 initiates the transaction by selecting the chip-based transaction option (as shown by arrow 402). Based on the selection of the chip-based transaction option, the terminal device 108 detects whether there is any electronic chip present within the first distance from the terminal device 108. The first distance may refer to the communication range, for example 10 cms, of the terminal device 108. In a scenario where the terminal device 108 does not detect the presence of any electronic chip within the first distance, the terminal device 108 may notify the user 104 that no electronic chip is detected for the chip-based transaction. In one exemplary scenario, the terminal device 108 detects the presence of the electronic chip 102 within the first distance from the terminal device 108 (as shown by arrow 404).

The terminal device 108 then establishes the bi-directional communication link 118 between the terminal device 108 and the electronic chip 102 (as shown by arrow 406), and prompts the user 104 to provide an authentication parameter associated with the electronic chip 102. In one embodiment, the terminal device 108 may be configured to implement one or more authentication schemes that are known in the art for ensuring that the bi-directional communication link 118 is established with only genuine electronic chips. Examples of such authentication schemes may include static data authentication (SDA), dynamic data authentication (DDA), and/or combined DDA with application cryptogram generation.

The user 104 provides the first authentication parameter to the terminal device 108 (as shown by arrow 408). In one example, the user 104 places a finger on a fingerprint scanner (as shown in FIG. 7) of the terminal device 108 for providing a fingerprint (i.e., the first authentication parameter) to the terminal device 108. In another example, a camera of the terminal device 108 scans the retina of the user 104 as the first authentication parameter. In another example, the camera of the terminal device 108 scans the faceprint of the user 104. In another example, the camera of the terminal device 108 records a gesture made by the user 104 as the first authentication parameter.

Based on the first authentication parameter of the user 104, the terminal device 108 generates an authentication request (as shown by arrow 410) and communicates the authentication request to the electronic chip 102 by way of the bi-directional communication link 118 (as shown by arrow 412). The authentication request includes the first authentication parameter of the user 104. The electronic chip 102 receives the authentication request and compares the first authentication parameter included in the authentication request with the sample authentication parameters stored therein (as shown by arrow 414). The electronic chip 102 determines that authentication is successful when the first authentication parameter matches any of the sample authentication parameters. The electronic chip 102 determines that authentication is unsuccessful when the first authentication parameter does not match any of the sample authentication parameters. In a scenario where the first authentication parameter does not match any of the sample authentication parameters, the electronic chip 102 may communicate a message to the terminal device 108 indicating that the authentication has failed. In such a scenario, the user 104 may reinitiate the transaction and provide another authentication parameter.

In a non-limiting example, it is assumed that the first authentication parameter matches a first sample authentication parameter. In such a scenario, the electronic chip 102 selects the default payment mode from the payment modes that are added to the electronic chip 102 (as shown by arrow 416). In one embodiment, the default payment mode is already set by the user 104. In another embodiment, the electronic chip 102 may automatically select the default payment mode based on one or more selection parameters, such as frequency of use of the payment modes, merchant categories, spending limit of the payment modes, or the like. For example, the electronic chip 102 may select a payment mode as the default payment mode that has a maximum frequency of use (i.e., a first selection parameter of the one or more selection parameters). In another example, the electronic chip 102 may determine that the user 104 has always used a first payment mode for purchases at grocery stores, and the current transaction is also for grocery purchase. In such a scenario, the electronic chip 102 may select the first payment mode as the default payment mode based on the merchant category (i.e., a second selection parameter of the one or more selection parameters). In another example, the electronic chip 102 may select the default payment mode based on the first authentication parameter of the user 104. When each payment mode added to the electronic chip 102 has a specific sample authentication parameter linked to it, the electronic chip 102 may select that payment mode as the default payment mode for which the sample authentication parameter matches the first authentication parameter (i.e., a third selection parameter of the one or more selection parameters).

Based on the selection of the default payment mode, the electronic chip 102 generates an authentication response (as shown by arrow 418). The authentication response includes the details of the default payment mode in an encrypted format. The electronic chip 102 communicates the authentication response to the terminal device 108 by way of the bi-directional communication link 118 (as shown by arrow 420). The terminal device 108 receives the authentication response from the electronic chip 102 and displays the details of the default payment mode on the graphical interface to the user 104 (as shown by arrow 422). In one example, when the default payment mode is a transaction card, the terminal device 108 may display last four digits of a transaction card number of the transaction card. In another example, when the default payment mode is a digital wallet, the terminal device 108 may display a wallet ID of the digital wallet. In another example, the terminal device 108 may display a username (for example, a unique identifier assigned to the payment mode) associated with the default payment mode. The terminal device 108 may prompt the user 104 to select the default payment mode for executing the transaction. In one embodiment, the terminal device 108 may further present a first option to the user 104 to reject the default payment mode and request for another payment mode from the electronic chip 102 to execute the transaction. An exemplary scenario where the user 104 selects the default payment mode for carrying out the transaction, is described in conjunction with FIG. 4B and another exemplary scenario where the user 104 rejects the default payment mode and chooses another payment mode that is different from the default payment mode for carrying out the transaction is described in conjunction with FIG. 4C.

With reference to FIG. 4B, it is assumed that the user 104 selects the default payment mode for the transaction (as shown by arrow 424 a). Based on the selection of the default payment mode, the terminal device 108 generates an authorization request for authorizing the transaction (as shown by arrow 426). The authorization request includes the details of the default payment mode and transaction details of the transaction. The transaction details of the transaction may include a transaction amount of the transaction, a transaction time, a transaction date, an authentication indicator, the electronic chip ID of the electronic chip 102, or the like. The authentication indicator may indicate that the authentication is successful. In one example, the authorization request is pursuant to one or more standards for the interchange of transaction messages, such as the ISO8583 standard.

The terminal device 108 communicates the authorization request to the acquirer server 110 (as shown by arrow 428). The acquirer server 110 receives the authorization request from the terminal device 108 and identifies a payment network that corresponds to the transaction, as known by those skilled in the art. The acquirer server 110 communicates the authorization request to the payment network server 112 of the identified payment network (as shown by arrow 430). The payment network server 112 receives the authorization request and identifies the issuer that corresponds to the transaction, as known by those skilled in the art. Once the issuer is identified, the payment network server 112 communicates the authorization request to the issuer server 114 of the identified issuer (as shown by arrow 432). The issuer server 114 verifies the details of the default payment mode and processes the transaction based on the successful verification of the default payment mode. The issuer server 114 generates an authorization response indicating the approval of the transaction (as shown by arrow 434). The issuer server 114 further communicates the authorization response to the payment network server 112 (as shown by arrow 436). The payment network server 112 receives the authorization response and communicates the received authorization response to the acquirer server 110 (as shown by arrow 438). The acquirer server 110 communicates the authorization response to the terminal device 108 (as shown by arrow 440). By way of the authorization response, the terminal device 108 is notified whether the transaction has been approved or declined by the issuer server 114. The terminal device 108 displays on the rendered graphical interface, a message to indicate whether the transaction is approved or declined (as shown by arrow 442). When the transaction is approved, the transaction amount of the transaction is charged to the default payment mode of the user 104. In a scenario where the terminal device 108 is an ATM, cash equivalent to the transaction amount is dispensed at the terminal device 108 when the transaction is approved.

With reference to FIG. 4C, it is assumed that the user 104 rejects the default payment mode (as shown by arrow 424 b) and selects the first option requesting the terminal device 108 to retrieve details of remaining payment modes from the electronic chip 102 (as shown by arrow 444). Based on the selection of the first option, the terminal device 108 communicates a first request to the electronic chip 102 by way of the bi-directional communication link 118 for retrieving the details of the remaining payment modes (as shown by arrow 446). The electronic chip 102 receives the first request and communicates a first response including the encrypted details of the remaining payment modes to the terminal device 108 (as shown by arrow 448).

The terminal device 108 receives the first response and displays the details of the remaining payment modes on the graphical interface for selection (as shown by arrow 450). In one example, the user 104 may select a second payment mode from the remaining payment modes for carrying out the transaction (as shown by arrow 452). Based on the selection of the second payment mode, the terminal device 108 generates the authorization request (as shown by arrow 454). The authorization request includes the details of the second payment mode and the transaction details of the transaction.

The terminal device 108 communicates the authorization request to the acquirer server 110 (as shown by arrow 456). The acquirer server 110 receives the authorization request from the terminal device 108 and identifies a payment network that corresponds to the transaction, as known by those skilled in the art. The acquirer server 110 communicates the authorization request to the payment network server 112 of the identified payment network (as shown by arrow 458). The payment network server 112 receives the authorization request and identifies the issuer that corresponds to the transaction, as known by those skilled in the art. Once the issuer is identified, the payment network server 112 communicates the authorization request to the issuer server 114 of the identified issuer (as shown by arrow 460). The issuer server 114 verifies the details of the second payment mode and processes the transaction based on the second payment mode. The issuer server 114 generates the authorization response indicating the approval of the transaction (as shown by arrow 462). The issuer server 114 further communicates the authorization response to the payment network server 112 (as shown by arrow 464). The payment network server 112 receives the authorization response and communicates the received authorization response to the acquirer server 110 (as shown by arrow 466). The acquirer server 110 communicates the authorization response to the terminal device 108 (as shown by arrow 468). The terminal device 108 displays on the rendered graphical interface, a message to indicate whether the transaction is approved or declined (as shown by arrow 470). When the transaction is approved, the transaction amount of the transaction is charged to the second payment mode. In a scenario where the terminal device 108 is an ATM, cash equivalent to the transaction amount is dispensed at the terminal device 108 when the transaction is approved.

FIGS. 5A and 5B, collectively represent a process flow diagram 500 that illustrates an exemplary scenario for conducting a split transaction using the electronic chip 102, in accordance with an exemplary embodiment of the disclosure. The user 104 may have activated and stored the details of the payment modes in the electronic chip 102. The user 104 may utilize the terminal device 108 for conducting the split transaction (i.e., a transaction for which a transaction amount is split across multiple payment modes) using the electronic chip 102.

The terminal device 108 renders the graphical interface for presenting the chip-based transaction option and the card-based transaction option to the user 104. The user 104 initiates the transaction by selecting the chip-based transaction option (as shown by arrow 502). Based on the selection of the chip-based transaction option, the terminal device 108 detects whether there is any electronic chip present within the first distance from the terminal device 108. In one exemplary scenario, the terminal device 108 detects the presence of the electronic chip 102 within the first distance from the terminal device 108 (as shown by arrow 504). The terminal device 108 then establishes the bi-directional communication link 118 between the terminal device 108 and the electronic chip 102 (as shown by arrow 506), and prompts the user 104 to provide an authentication parameter associated with the electronic chip 102.

The user 104 provides the first authentication parameter to the terminal device 108 (as shown by arrow 508). Based on the first authentication parameter of the user 104, the terminal device 108 generates an authentication request (as shown by arrow 510) and communicates the authentication request to the electronic chip 102 by way of the bi-directional communication link 118 (as shown by arrow 512). The authentication request includes the first authentication parameter of the user 104. The electronic chip 102 receives the authentication request and compares the first authentication parameter included in the authentication request with the sample authentication parameters stored therein (as shown by arrow 514).

In a non-limiting example, it is assumed that the first authentication parameter matches one of the sample authentication parameters. In such a scenario, the electronic chip 102 selects the default payment mode from the payment modes stored therein (as shown by arrow 516). The selection of the default payment mode has been described in the foregoing description of FIG. 4A. Based on the selection of the default payment mode, the electronic chip 102 generates an authentication response (as shown by arrow 518). The authentication response includes the details of the default payment mode. The electronic chip 102 communicates the authentication response to the terminal device 108 by way of the bi-directional communication link 118 (as shown by arrow 520). The terminal device 108 receives the authentication response from the electronic chip 102 and displays the details of the default payment mode on the graphical interface to the user 104 (as shown by arrow 522).

With reference to FIG. 5B, the terminal device 108 displays a split payment option in addition to the first option (as described in FIG. 4A) on the graphical interface (as shown by arrow 524). The split payment option allows the user 104 to split the transaction amount of the transaction across multiple payment modes. For example, the transaction amount of the transaction may be $2,000 and the user 104 may want to split $2,000 across two payment modes. In such a scenario, the user 104 selects the split payment option (as shown by arrow 526). Based on the selection of the split payment option, the terminal device 108 communicates the first request to the electronic chip 102 for obtaining the details of the remaining payment modes (as shown by arrow 528). The electronic chip 102 receives the first request and communicates the details of the remaining payment modes to the terminal device 108 (as shown by arrow 530). The terminal device 108 displays the details of all the payment modes including the default payment mode on the graphical interface to the user 104 (as shown by arrow 532). From the displayed payment modes, the user 104 may select any number of payment modes across which the user 104 wants to split the transaction amount. In one example, the user 104 selects the first and second payment modes for carrying out the transaction (as shown by arrows 534 a and 534 b). In one example, the first and second payment modes are first and second transaction cards that are added to the electronic chip 102. In another example, the first and second payment modes are first and second digital wallets that are added to the electronic chip 102. In another example, one of the first and second payment modes is a transaction card and the other is a digital wallet.

Based on the selection of the first and second payment modes, the terminal device 108 prompts the user 104 to provide details of first and second parts of the transaction amount that are to be charged to the first and second payment modes, respectively. The user 104 then specifies the first and second parts that are to be charged to the first and second payment modes, respectively (as shown by arrow 534 b). For example, when the transaction amount is $2,000, the first part may be equal to $1,200 and the second part may be equal to $800.

The terminal device 108 then generates two authorization requests, for example, first and second authorization requests, for initiating authorization of the split transaction from the first and second payment modes, respectively (as shown by arrow 536). The terminal device 108 communicates the authorization requests to the acquirer server 110 (as shown by arrow 538). The acquirer server 110 receives the authorization requests from the terminal device 108 and identifies payment network/s that correspond/s to the first and second payment modes, as known by those skilled in the art. In one example, the first and second payment modes may be associated with the same payment network. In another example, the first and second payment modes may be associated with different payment networks. For the sake of brevity, it is assumed that the first and second payment modes are associated with the same payment network.

The acquirer server 110 then communicates the authorization requests to the payment network server 112 of the identified payment network (as shown by arrow 540). The payment network server 112 receives the authorization requests and identifies issuer/s that correspond/s to the first and second payment modes, as known by those skilled in the art. In one example, the first and second payment modes may be associated with the same issuer. In another example, the first and second payment modes may be associated with different issuers. For the sake of brevity, it is assumed that the first and second payment modes are associated with the same issuer. Once the issuer is identified, the payment network server 112 communicates the authorization requests to the issuer server 114 of the identified issuer (as shown by arrow 542). The issuer server 114 verifies the details of the first and second payment modes and approves the split transaction. The issuer server 114 generates two authorization responses, for example first and second authorization responses (as shown by arrow 544). The first authorization response may correspond to the first authorization request and the second authorization response may correspond to the second authorization request. The issuer server 114 further communicates the authorization responses to the payment network server 112 (as shown by arrow 546). The payment network server 112 receives the authorization responses and communicates the received authorization responses to the acquirer server 110 (as shown by arrow 548). The acquirer server 110 communicates the authorization responses to the terminal device 108 (as shown by arrow 550). The terminal device 108 displays on the rendered graphical interface, a message to indicate whether the split transaction is approved or declined (as shown by arrow 552).

In one embodiment, the user 104 may reject the default payment mode for the transaction and may split the transaction amount across one or more remaining payment modes. In one embodiment, the terminal device 108 may be configured to authorize the transaction offline. For example, if a payment mode selected by the user 104 for conducting the transaction has a spending limit that is less than the transaction amount, the terminal device 108 may either decline the transaction offline or may prompt the user 104 to select another payment mode from the remaining payment modes. In another example, if a payment mode selected by the user 104 for conducting the transaction has an overdraft limit that is greater than or equal to the transaction amount, the terminal device 108 may approve the transaction offline. In another example, if a payment mode selected by the user 104 for conducting the transaction is expired, the terminal device 108 may either decline the transaction offline or may prompt the user 104 to select another payment mode from the remaining payment modes. The information pertaining to the spending limit, the overdraft limit, the expiry date, or the like may be stored in the electronic chip 102 and may be communicated to the terminal device 108 by the electronic chip 102 when the corresponding payment mode is selected by the user 104 for carrying out the transaction.

FIGS. 6A-6C, collectively represent an exemplary scenario 600 that illustrates first through sixth user interface (UI) screens 602, 604, 606, 608, 610, and 612 rendered on the terminal device 108 for enabling users to conduct transactions at the terminal device 108, in accordance with an exemplary embodiment of the disclosure. In a non-limiting example, the terminal device 108 is shown to be a POS device in FIGS. 6A-6C, however in other embodiments, the terminal device 108 may be a POP device, a POI device, an ATM device, or the like.

When the user 104 interacts with the terminal device 108 for initiating the transaction, the first UI screen 602 is rendered on a display (not shown) of the terminal device 108. The first UI screen 602 may prompt the user 104 to select one of a ‘chip-based transaction’ button 614 or a ‘card-based transaction’ button 616. The ‘chip-based transaction’ button 614 represents the chip-based transaction option and the ‘card-based transaction’ button 616 represents the card-based transaction option. When the user 104 selects or activates the ‘card-based transaction’ button 616, the transaction is processed based on a conventional four-party system or a conventional three-party system as known by those skilled in the art. When the user 104 selects the ‘chip-based transaction’ button 614, the terminal device 108 may render the second UI screen 604.

The second UI screen 604 may display a message requesting the user 104 to provide the first authentication parameter (e.g., a fingerprint). The second UI screen 604 may further display a first submit button 618, which is selectable by the user 104 for submitting the first authentication parameter. When the user 104 provides the first authentication parameter (e.g., a fingerprint) and selects or activates the first submit button 618, the terminal device 108 may communicate the authentication request, including the first authentication parameter, to the electronic chip 102. After the electronic chip 102 performs authentication, the terminal device 108 receives the authentication response including the details of the default payment mode. After receiving the authentication response, the terminal device 108 may render the third UI screen 606.

The third UI screen 606 displays a ‘default payment mode’ button 620. The ‘default payment mode’ button 620 corresponds to the default payment mode. The third UI screen 606 further displays a message in a first text box 622 to inquire whether the user 104 wants to continue the transaction using the default payment mode.

Since the user 104 is allowed to add any number of payment modes to the electronic chip 102 and link all the added payment modes to one or more sample authentication parameters, the user 104 is saved from the hassle of carrying multiple payment modes and remembering passwords or PINs of all the payment modes. Technological improvements in the electronic chip 102 enable the electronic chip 102 to store the details of both transaction cards and digital wallets, thus offering a one-stop solution to the user 104 for all types of transactions. Since the electronic chip 102 is either placed on a user's wearable device (as shown in FIG. 2A) or placed under the user's skin (as shown in FIG. 2B), the likelihood of skimming fraud is reduced. In addition, details stored in the electronic chip 102 can only be retrieved by way of the first authentication parameter of the user 104 that matches one of the sample authentication parameters stored in the electronic chip 102, thus making the electronic chip 102 immune to skimming fraud. Technological improvements in the terminal device 108 allow the terminal device 108 to establish the bi-directional communication link 118 only with genuine electronic chips. As the electronic chip 102 and the terminal device 108 perform the authentication process offline by way of a short-range wireless communication link (i.e., the bi-directional communication link 118), the processing overhead of the issuer server 114 and the processing time for the transaction are reduced.
